Furan-2,3-diones, structurally related to ascorbic acid, show potential antitumour physiological activity.Previous studies on this class of compounds have been devoted to their reactivity and thermal decomposition in solutions.It was reported, that 5-(p-R-phenyl)furan-2,3-dione with R=H, CH3, Cl, Br undergoes thermal decomposition in benzene and methyl alcohol solutions with elimination of carbon monoxide, the reaction product being able to react further to afford stable products.On another side, previous studies on the photochemical decomposition of these compounds in an Ar matrix at 15 K, in a KBr matrix and in solution have demonstrated the elimination of carbon dioxide as being the first reaction step.The reaction intermediates, as evidenced by Fourier Transform IR spectrometry, are either a ketene and/or cyclopropenone.
